Pleural fibroma: review based on 12 cases.

The authors report 12 cases of pleural fibroma, which is a rare benign tumo r, usually discovered incidentally. However, these tumors are sometimes ass ociated with a paraneoplastic syndrome, or may lead to compressive symptoms related to their large size. Radical resection is mandatory because recurr ence may occur, sometimes several years later with a malignant behavior. Lo ng-term follow-up is therefore necessary to detect any recurrence, particul arly when certain prognostic factors are initially present.
